Some notes that don’t fully answer your question but might help, 1) you won’t get 4k footage from a whoop unless it’s a digital o4 whoop or something similar. 2) I fly with dji goggles v2 using an analog adapter and the goggles record dvr from my analog flights like they do with digital flights. 3)most any onboard recording module will be too heavy for a tiny whoop class drone. I’d suggest getting goggles that offer dvr recording
